What is the median of the ages of minor children?

Variance of the first $$1$$ natural numbers is.

Mean and standard deviation of a data are $$48$$ and $$12$$ respectively. The coefficient of variation is.

What is the mean deviation about the mean for the data $$4, 7, 8, 9, 10, 12, 13, 17$$?

Given $$\sum (x-\bar{x})^2=48, \bar{x}=20$$ and $$n=12$$. The coefficient of variation is.

If the variance of $$14, 18, 22, 26, 30$$ is $$32$$, then the variance of $$28, 36, 44, 52, 60$$ is.

The variance of $$10, 10, 10, 10$$ is.

Calculate the coefficient of range from the following discrete (ungrouped) frequency distribution of marks of 60 students.

If x is the average(arithmetic mean) of $$5$$ consecutive odd integers, what is the median of integers?

If coefficient of range is $$0.092$$ and the largest value is $$71$$, the range is?
